the diagonal in a paralleogram is not equal but the diagonals in the rectangle are congruent
this is because the opposite sides of a parallelogram and rectangle are same parallel to each other but the adjacent sides of a parallelogram is not perpendicular where as the adjacent sides of rectangle is perpendicular to each other.
What else can I help you with?
What is true of the diagonals of a rectangle that isn't true of the diagonals of a parallelogram?
They are of equal length.
If the diagonals of a parallelogram are congruent then the parallelogram may or may not be a rectangle. A.True B.False?
True because the diagonals of a rectangle are equal in lengths
What shape has 2 pairs of parallel sides and equal length diagonals which do not cross at 90 degrees?
A parallelogram (or rectangle) which is not a rhombus (or square).
If ABCD is a parallelogram and the two diagonals are equal find the measure of angle ABC?
90 degrees - the parallelogram is a rectangle (or a square) if the diagonals are equal.
Do all parallelogram have diagonals of equal length?
yes
If a parallelogram is a rectangle then it's diagonals are what?
Its diagonals are equal in length
What is true of the diagonals of a rectangle that isn't true of the diagonals of a parallelogram?
They are of equal length.
Is every property of parallelogram also a property of all rectangles?
No as for example the diagonals of a rectangle are equal in length whereas they are not equal in length in a parallelogram
Is a rectangle a special case of parallelogram why?
yes it is it is a parallelogram of its angles is right or The two diagonals are equal in length
Is diagonals of a parallelogram are alwayssometimesnever congruent?
Sometimes as when the parallelogram is in the form of a rectangle then its diagonals are of equal lengths.
If the diagonals of a parallelogram are congruent then the parallelogram may or may not be a rectangle. A.True B.False?
True because the diagonals of a rectangle are equal in lengths
What is a quadrilateral with diagonals that bisect each other?
The diagonals of any parallelogram (square, rhombus, rectangle, rhomboid) bisect each other. The difference is the the diagonals are equal in length for a square and rectangle, and not equal for a rhombus or rhomboid (oblique diamond).
What is true of the diangonals in the rectangle that isn't true of the diaagonals ofthe parallelogram?
Diagonals are equal in a rectangle but not in a parallelogram.
What shape has 2 pairs of parallel sides and equal length diagonals which do not cross at 90 degrees?
A parallelogram (or rectangle) which is not a rhombus (or square).
A quadrilateral with equal diagonals and no right angles?
An isosceles trapezoid will have diagonals of equal length but will never contain right angles by definition. A square and rectangle will have diagonals of equal length but will contain 4 right angles. A rhombus and any other parallelogram that does not contain right angles will not have diagonals of equal length.
If ABCD is a parallelogram and the two diagonals are equal find the measure of angle ABC?
90 degrees - the parallelogram is a rectangle (or a square) if the diagonals are equal.
The diagonals of a parallelogram must be what?
The diagonals of a parallelogram are congruent (equal in length) and bisect each other.
